Edinburgh's 18th-century City Chambers were built over the sealed-off remains of Mary King's Close, and the lower levels of this medieval Old Town alley have survived almost unchanged amid the foundations for 250 years. Now open to the public, this spooky, subterranean labyrinth gives a fascinating insight into the everyday life of 17th-century Edinburgh. Costumed characters lead tours through a 16th-century townhouse and the plague-stricken home of a 17th-century gravedigger. Advance booking recommended.
The scripted tour, complete with ghostly tales and gruesome tableaux, can seem a little naff, milking the scary and scatological aspects of the close's history for all they're worth. But there are also things of genuine interest to see: there's something about the crumbling 17th-century tenement room that makes the hair rise on the back of your neck, with tufts of horsehair poking from collapsing lath-and-plaster walls that bear the ghost of a pattern, and the ancient smell of stone and dust thick in your nostrils.
In one of the former bedrooms off the close, a psychic once claimed to have been approached by the ghost of a little girl called Annie. It's hard to tell what's more frightening – the story of the ghostly child, or the bizarre heap of tiny dolls and teddies left by sympathetic visitors.
